R-C Debouncing
Thaum qhov hloov pauv nyob rau hauv lub xeev qhib qhov hluav taws xob thoob plaws lub capacitor nyob twj ywm xoom. Thaum pib, thaum hloov pauv qhib lub capacitor them los ntawm R1 thiab R2 resistor. Nyob rau hauv qhov xwm txheej bouncing, lub capacitor nres qhov voltage ntawm Vin kom txog thaum nws ncav cuag Vcc lossis hauv av.
Yog li ntawd, dab tsi yog txhais los ntawm Debouncing?
debounce yog ib yam ntawm cov cuab yeej kho vajtse lossis software uas ua kom ntseeg tau tias tsuas yog ib lub teeb liab nkaus xwb yuav ua rau ib qho qhib lossis kaw ntawm kev sib cuag. Thaum koj nias tus yuam sij ntawm koj lub khoos phis tawj keyboard, koj cia siab tias yuav muaj ib qho kev sib cuag los ntawm koj lub computer.
Tsis tas li ntawd, lub sijhawm debounce zoo yog dab tsi? Qhov nruab nrab tus kws ntaus ntawv ntaus ntawv feem ntau nyob rau hauv speeds ntawm 50 mus rau 80 wpm - txog 250-400 cim ib feeb. Qhov ntawd yog 4 - 6 cim ib ob. 50 ms ncua = 20 cim ib ob! 300 ms ncua = 3.33 cim ib ob.
Hais txog qhov no, txhais li cas los ntawm kev hloov Debouncing?
Glossary Term: debounce Txhais . Hluav taws xob tiv tauj hauv mechanical pushbutton hloov feem ntau ua thiab tawg tiv tauj ob peb zaug thaum lub khawm yog thawj thawb. A debounce Circuit Court tshem tawm cov teeb liab tshwm sim, thiab muab kev hloov pauv huv ntawm nws cov zis. Ntxiv: Hloov Bounce thiab lwm yam qias neeg me me
Tus Debouncer ua haujlwm li cas?
R-C Debouncing Lub capacitor hauv Circuit Court lim cov kev hloov tam sim hauv lub teeb liab hloov. Thaum hloov yog Nyob rau hauv qhib lub xeev qhov voltage hla lub capacitor nyob zero. Thaum pib, thaum hloov yog qhib lub capacitor them los ntawm R1 thiab R2 resistor.
